The popularity is further increasing as Android is the primary choice of OS for maximum smartphone users. Concerning this, the whole community of Android developers has to reinvent the wheel of technical implications and provide a satisfactory experience. One of the ways to do that is getting hands on the most profound Android libraries comprising of tools, extensions, and plugins.

For the sake of successful and timely Android app development for enterprises, developers need to be well-versed with the latest tools. Thus, we bring you here the list of the 20 best Android libraries that are must to consider in 2021 for enhancing the development task.

What are Android Libraries?

Android libraries are a set of Android mobile app development-based modules available for developers to create a different set of functionalities, interface, and design elements. The support libraries are divided into two categories. One that is available for the new Android version that helps to upgrade the older versions into new. And, the other set of Android libraries are standalone that work best for all versions of Android OS and allow developers to make specific additions and changes in a hassle-free manner.

Importance of Using Android Support Libraries

1. Add New Features

New Android versions keep coming to the marketplace. But users need not buy the latest version of the device to get new updates and features. Android libraries help developers to add the functionality of automatic updates via regular notifications at certain time intervals. Developers can add new features as to how their apps work, especially on the devices that still run on older versions.

2. Stay Updated

Updating from one Android platform to another is a cumbersome task. And, you see such updates happen only once a year. Using Android support libraries, developers can add the functionality of automatic updates to the device. It helps to add on new integrations and functionalities from time to time.
